Compression of Woven Reinforcements: A Mathematical Model

A mathematical model for prediction of the compressional behaviour of woven reinforcement is described. The model accounts for the compression of yarns and the change of yarn crimp under pressure applied to a fabric layer. Compression curves of glass rovings are studied experimentally and serve as input for simulation of fabric compression. The model is tested against experimental data for glass reinforcement for the lower and the higher pressure range.
